Class FrameStack

  org.prorefactor.treeparser01.FrameStack

public class FrameStack
extends java.lang.Object

Keeps a stack of most recently "referenced" frames. A frame may be "referenced" at up to two different occassions. Once when the frame is created (like in a DEFINE FRAME statement), and once when the frame is "initialized" (like in a DISPLAY statement). The frame's scope is determined at the time it is initialized. Also deals with BROWSE widgets and the fields in those.
